PROCESS OF MANUFACTURING MATERIALS SIMILAR T O'WUOD FROM FIBROUSREFUSE;

SPECIFICATION forming part of Letters Patent No. 625,450, dated. May 23, 1899.

Application filed February 4, 1899. S ri l N 7043563. (N0 specimens.)

To all whom it may concern:

Be it known that I, J OHANNES KAISER, a subject of the King of Prussia, German Emperor, and a resident of Berlin, Prussia, Germany, have invented certain Improvements in Processes of ManufacturingMaterials Similar to Wood from Fibrous Refuse, of which the following is the specification.

My invention relates to the manufacture of materials similar to wood; and its object is to use for this purpose waste of small value.

My invention will be hereinafter fully described, and its novel features carefully defined in the claims.

I take any kind of fibrous refuse-such as distillers wash, malt=husks, apple-squash, and other fibrous refuse matter from the processes of brewing andd'istilling or wine manufacture-dry it, and separate it from greater impurities. I then produce a fiuXing by using a lye of soda, from which results a thickish paste which saponifies by the addition of resins. The lye is then washed out of this soaplike mass, and the residues of water are then removed by pressing. Afterward it is profitable to mix the mass with a little ground wood or the like, and in order to procure a higher degree of cohesion and brilliancy any agglutinant, such as grape-sugar, may be admixed and the whole then dried in thin layers. The dried plates are now pulverized and represent, after being kneaded, a mass capable of being formed and very similar to wood, both as to appearance and durability.

After having now particularly described the nature of my invention, what I claim is' 1. The process of manufacturing a plastic mass similar to wood, which consists in fluxing a fibrous refuse, then saponifying the resultant material, then subjecting the material to pressure, then mixing ground wood and an agglutinant with said material, and then drying the resultant mass.

2; The process of manufacturing a plastic material similar to wood, which consists in fluxing a fibrous refuse with lye, then saponifying the resultant material with resin, then subjecting the material to pressure, then mixing ground wood and an agglutinant with the said material, then drying the said mixture and finally kneading the mass.

3. The process of manufacturing a plastic material similar to wood, which consists in fluxing a fibrous refuse with lye, then saponifying the resultant material with resin, then subjecting the material to pressure, then mixing ground wood and grape-sugar with the said material, then drying the said mixture and finally kneading the mass.

In witness whereof I have hereunto set my hand in presence of two witnesses.

JOHANNES KAISER.
